What's Wrong with My Big Brother

HD
Subbed
ONA
After transmigrating into a cultivation world and becoming the eldest disciple of the Xiaoyao Sect, Dongfang Xianyun discovers that he doesn’t fit the mold of a typical protagonist from a transmigration novel. Following a few experiments, he decides that his best chance for survival is to latch onto his second junior brother, Yin Feixing—who perfectly embodies the classic protagonist archetype. The story follows the chaotic and uproarious life at the Xiaoyao Sect, featuring Dongfang Xianyun, the "protagonist" Yin Feixing, their eccentric third junior sister, and their lively, adorable youngest junior brother.
